In the case of an apartment or a mixed-use building, a non-powered fan is installed at the upper part of the exhaust duct so that air in the building is properly sucked and discharged. Since the exhaust duct was not made smoothly and the exhaust duct was buried in a part of the building so that the ventilation system of each household was connected, the volume ratio was reduced. The rough surface of the exhaust duct increased air resistance and caused air leakage. The exhaust was not done properly.

In addition, the conventional ventilation hood and ventilation system only by the bathroom fan is not designed to supply fresh air to the room, but because it is designed to exhaust the internal air, the outside air did not flow into the room properly, and thus the exhaust performance of the range hood. Because of this deterioration, the food odor could not be properly discharged and severe noise was generated from the fan motor when the hood was operated.

In addition, since the ventilation system of the kitchen, bathroom, and living room must be individually configured and installed, the cost is increased. In particular, indoors with two or more toilets require the installation of fan motors as many as the number of toilets. Caused.

Therefore, the air of the kitchen sucked into the suction port 36 of the range hood damper 21 by the suction force of the exhaust fan motor 20 passes through the extract air filter 19 of the exhaust line 13 and is shown in FIG. 3. As described above, it is not introduced into the exchanger 18 and is discharged to the exhaust duct 6 through the exhaust hole 30 of the bypass damper 22.

Such a building ventilation system of the present invention has several advantages.

First, a plurality of ventilation ducts inside a building are connected to one ventilation unit 10 to supply external fresh air to an indoor living room, and discharge all polluted air from bathrooms and kitchens to the outside. The ventilation unit 10 can be used.

That is, the air supply line 12 of the ventilation unit 10 is connected to the external air duct 1 for sucking external air and the air supply duct 2 for supplying the sucked external air to the room, and the ventilation unit 10 is connected. In the exhaust line 13), the intake duct 3 for sucking air in the bathroom, the range hood duct 4 for sucking the smell of food in the kitchen, and the air of the sucked bathroom and kitchen are discharged to the outside. Since the exhaust duct 6 is connected, when operating one ventilation unit 10, the fresh air is forcibly supplied to the living room and the room, and the polluted air inside the kitchen and bathroom is forced out and discharged to the outside. do.

Therefore, it is possible to ventilate the entire interior of a building with a single device has the advantages of reducing the installation cost, installation space reduction, air shortening according to the reduction of installation work compared to the conventional ventilation device was distributed and installed in several.

In addition, since the smell of the kitchen is sucked by the exhaust fan motor 20 of the ventilation unit 10 and discharged to the outside, the fan motor does not need to be installed inside the hood. In addition, since the ventilation unit 10 is usually installed outdoors or on the porch, the noise of the conventional fan motor is not generated even when the range hood 5 is operated to discharge the smell of the kitchen. Accordingly, the range hood 5 is removed. Watching TV and listening to music are not interrupted at all.

And since the fresh air outside the forced air supply to the living room or each room by the air supply fan motor 15, the ventilation effect is excellent and the discharge performance of the range hood 5 is improved by the appropriately supplied external air Has
